Russian Health Watchdogs Eye Hantavirus Outbreak on Atlantic Cruise Ship

Russian health authorities are closely tracking reports of a hantavirus case on a cruise liner crossing the Atlantic Ocean. The Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing, known as Rospotrebnadzor, confirmed Monday it is monitoring the situation aboard the MV Hondius, a polar expedition vessel operated by Dutch company Oceanwide Expeditions.

The ship was en route from Ushuaia, Argentina, to Cape Verde when two passengers died from an acute respiratory infection, South Africa’s Ministry of Health confirmed Sunday evening. Both victims were aboard the MV Hondius. While South African officials have not publicly named the specific pathogen, Rospotrebnadzor’s statement refers to the presence of hantavirus—a rare but severe rodent-borne illness that can cause respiratory failure.

“From the first publication, Rospotrebnadzor has kept under control the development of the situation connected with the registration of hantavirus on board the cruise ship MV Hondius, now in the Atlantic Ocean,” the agency said in a statement.

The MV Hondius, a small ice-class vessel built for polar voyages, typically carries around 170 passengers and 80 crew. Oceanwide Expeditions has not yet issued a public comment on the deaths or the suspected virus. The ship’s current status and the health of remaining passengers remain unclear.

Hantavirus is not typically associated with cruise ships, making this case unusual. The virus spreads through contact with rodent droppings or urine, not person-to-person, which raises questions about possible contamination onboard. Health officials in multiple countries are now coordinating to assess risks and prevent further spread.
